The jedi knight story would be most similar to Revan's story in kotor 1.

Kira Carsen=Bastila
astromech droid
dark side tempations
on a quest to ''save the galaxy''
fights the big bad guy at the end
+ a lot of other little things

* * *
Now... about his abilities.''Real'' jedi and sith are not divided so strongly into classes as they are in the game.This division is a gameplay mechanic more than anything else,not a lore mechanic.
So basicaly Revan as well as The Hero of Tython could throw rocks at you,be expert at lightsaber combat + some dark side abilities + *put random force ability here*,ect,ect.
